If you're afraid of being Tor-censored, you better leave the place altogether. I know that might sound nuts, but if you think about it, you're living under a very authoritarian regime. Censoring people who use Tor is the practice of "everyone guilty until proven innocent". I'd absolutely not want to live and make a family in such country.
You can also download Tor Browser by email message
You should use a private email server, before that becomes censored. Also, you could perhaps use the free wifi of cafeterias to get into torproject.org?
I am not saying that someone will arrest you for using Tor or you will ever experience any trouble by using Tor. But I think if you want to keep your privacy protected, you shouldn't let them know that you are protecting your privacy. Sounds confusing? The best way to keep a prisoner from escaping is to make sure he never knows he's in prison. In other words, if you publicly use Tor, they know you are either doing something wrong or are trying to protect your privacy. Gotcha, we know you are not an ordinary user, we will keep an eye on you, in case something bad happens.
These are my thoughts, that's why I think absolutely everyone should try to keep it secret from their ISP that they use Tor.
